Quartz Tungsten Halogen (QTH) Sources Guide

Quartz Tungsten Halogen (QTH) Lamps have high visible and near infrared output, with little ultraviolet making them great for use in Incandescent Light Sources. The stability, filament structure and high color temperature make our lamps the best for many measurement and illumination applications. We offer 10 to 1000 W QTH systems.
